Albert L. Ortega/Getty Images(SAN DIEGO) -- Fans got a lot closer to Bryan Cranston than they realized, when the actor donned a lifelike Walter White mask while milling around the convention center Sunday during San Diego’s Comic-Con.

The 57-year-old actor came dressed as his character in the popular series Breaking Bad wearing a mask that gave him White’s iconic shaved head. As he took the stage for the show’s panel, he removed his mask — much to the surprise and delight of the audience.

He revealed that earlier he was able to chat with unsuspecting fans by disguising his voice in a “higher register.”

Cranston kept the gag going, according to Entertainment Weekly, by putting the mask on the table and speaking into it while answering questions. He got his co-star Aaron Paul to join in the fun, too.

Not surprisingly, Paul noted that his co-star was “the most professional person I’ve ever worked with but also the immature man I’ve ever experienced, as you can tell. Which is a beautiful combination.”
